Show HN: Cami.js – A no build, web component based reactive framework

Hi Everyone! My main motivation for making this was that I wanted something as powerful as Svelte or React but I wanted no build steps, no JSON API, and I wanted something as close to vanilla js as much as possible. I'm mainly a backend developer, and I wanted to simply return html with some interactive islands when I need to (whose components get 'hydrated' with by backend language's templates).

Some key ideas:

• It's centered around light dom web components • Uses a "reactive element", which uses observables for fine-grained reactivity • Rendering is done through lit-html's tagged templates • A pub/sub store • Easy immutability using immer (it powers the observable updates & also the reducers)

It's my first 'serious' library that I'm using in some work prototypes, and it's also my first 'real' open source project, so comments & feedback would be great!
